portion, equivalent to the product of unskilled average labor, or equal to a definite quantity of that unskilled labor.
The determination of exchange-value by means of labor-time implies, further, the fact that an equal quantity of labor is embodied in any given commodity, e. g., a ton of iron, no matter whether it is the work of A or B, that is to say, various individuals expend an equal amount of labor-time for the production of the same use-value of a given quality and quantity. It is thus assumed that the labor-time contained in a commodity is the labor-time necessary for its production, i. e., it is the labor-time which is required for the production of another specimen of the same commodity under the same general conditions of production.
The conditions of labor, which creates exchange value, as shown by the analysis of the latter, are social conditions of labor or conditions of social labor. Social, not in the ordinary, but in a special sense. It is a specific form of the social process. The homogeneous simplicity of labor means first of all equality of the labors of various individuals, a reciprocal relation of equality of their labors determined by the actual reduction of all kinds of labor to uniform labor. The labor of every individual, as far as it is expressed in exchange value possesses this social character of equality and finds expression in exchange value only in so far as it is a relation of equality with the labor of all other individuals.
Furthermore, the labor-time of a single individual is directly expressed in exchange value as universal
